Comparison of Cat Ages

by Ron Kurtus (revised 13 September 2011)

Cats age more rapidly than humans. One year for a cat is equivalent to over five years of human life.

In the various phases of its life, a cat has different nutritional and health care needs. Older cats suffer from the same ailments as elderly people, such as arthritis and loss of hearing and vision. A comparison of the actual age of your cat and the corresponding age of a human can give you a good idea of how to take care of your pet and also to understand its behavior.

The same is true for dogs and other animals.
